Robots to build Canada’s 9-story timber tower in just 90 days (interestingengineering.com)

Mass timer buildings are prefabricated structures made of (hopefully renewable) wood. The pieces are made in a factory and then able to be quickly constructed together on-site.

This can hopefully greatly reduce the amount of carbon in the atmosphere from producing a building. The cost of producing buildings in this method is also going down. Additionally, these mass timer buildings are typically more dense than single family homes, which can lead to more sustainable communities.

Aren't buildings made of lumber limited to 4 stories? And for good reason? Is that like a US only rule?

Yes, though it really depends on the city. They all have different rules. It's interesting how zoning rules shape a lot of how North America looks.

One type of building that's becoming more common are "five over one", where you build one floor with concrete and then floors over with wood. These buildings have gathered criticism for being super generic. https://en.m.wikipedia.org/wiki/5-over-1

Mass timber is a new method of construction, so cities have been updating their laws to reflect it.

Those 5 over 1 depicted look better than the concrete shoeboxes around here
